Richardson granted patent for dependent encryption keys

http://www.faqs.org/patents/app/20100296653

Today I was informed of yet another patent granted by the USPTO. The patent has to do with a series of dependant encryption keys with the ability to use one key to decrypt a whole series of encrypted packages each with different keys.

At the time I thought it was a really interesting approach with applications in areas where a series of products purchased by a customer could be unlocked with one master key (the latest key) if the results of each unlock were used to unlock the previous product.

Congratulations to Sean Burdick at Uniloc for working the many years to get this through the examination process.
